Products details

Formed by means of CIP (cold isostatic pressing) technique, isostatic graphite is characterized by its homogeneous structure and excellent isotropic electrical, thermal and mechanical properties. Sometimes it is purified in special-designed graphitization furnace to remove non-carbonaceous impurities. It is widely used in a variety of industrial and scientific engineering as a structural and/or functional material.Applications

Molds in continuous casting systems for making shaped steel, cast iron, copperSintering molds for cemented carbides, diamond tools and electronic componentsMolds for making shaped glassCrucibles for melting precious metals or alloysElectrodes for EDMHeating elements, heat shields, crucibles, boats in furnaces for pulling monocrystalline silicon or optical fibersAnodes for production of manganese dioxide, metallic magnesium & rare metals and etc.
